About

The Japan Meteorological Agency publishes its disaster prevention messages as Atom feeds at www.data.jma.go.jp. Four high-frequency feeds (regular, extra, eqvol, other) refresh every minute and hold at least the last ten minutes of messages. Four long-term feeds refresh hourly and hold several days. Each entry links to a message in the JMA XML format, whose schema, dictionary and code tables JMA publishes on its technical materials page.

Through Fibric, an operator polls the extra and eqvol feeds, pulls the linked messages for the areas you care about, and proposes a hold, a notice, or a site check for your approval, with a record of which message triggered it.

This is a reference listing. It documents what Fibric would read from JMA Disaster Prevention Information XML Feed and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • Regular feed: scheduled products such as forecasts, from regular.xml
  • Extra feed: unscheduled warnings and advisories, from extra.xml
  • Earthquake and volcano feed: bulletins from eqvol.xml
  • Other feed: messages outside the three categories, from other.xml
  • Long-term feeds regular_l, extra_l, eqvol_l and other_l, refreshed hourly with several days of entries
  • The linked JMA XML messages, described by the Ver. 1.3 format specification, XSD schema, dictionary and code tables

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Hold shipments into a warned prefecture

    Watch extra.xml for warnings in the prefectures you ship to and propose a hold on outbound orders until the warning clears.

    With Weather Hold

  • Tell staff about an earthquake or volcano bulletin

    Read eqvol.xml, match bulletins to the areas where you have sites, and propose a notice to the people on shift and a roster check.

    With Severe Weather Notice, Evacuation Roster

  • Prepare a property before a typhoon warning lands

    Take warnings from the extra feed and propose the preparation checklist for each affected building, with the message that triggered it attached.

    With Storm Prep

Requirements

  • An HTTP client that can poll Atom feeds and fetch the linked XML messages
  • A parser for the JMA XML format, using the published XSD schema and code tables
  • The area or prefecture codes you want to watch, taken from JMA's code tables
  • Daily download volume kept under 10 GB, or the source IP is blocked
Authentication
None. The feeds are public HTTP resources with no key or registration.

Limits

  • Feeds and messages are in Japanese; JMA publishes the specification and code tables in Japanese
  • High-frequency feeds hold only about the last ten minutes; a client that stops polling must recover from the long-term feeds
  • JMA blocks an IP that downloads more than 10 GB a day and states no liability for how the data is used
  • Service may stop or lag during server maintenance

Questions and answers

What is the difference between the high-frequency and long-term feeds?
The four high-frequency feeds (regular, extra, eqvol, other) update every minute and carry at least the last ten minutes of messages. The four long-term feeds with the _l suffix update hourly and carry several days of messages.
Is registration or a key needed for the JMA XML feeds?
No. The feeds at www.data.jma.go.jp/developer/xml/feed/ are open HTTP resources. JMA states that an IP address that downloads more than 10 GB in a day will be blocked.
What license covers JMA content?
JMA's Legal Notice applies its Terms of Use, based on the Public Data License (Version 1.0): cite the Japan Meteorological Agency as source and state when content was edited. JMA says content may be used under the CC BY license in place of its terms.
